Answer:
x = 9.7
x = 51.4
x = 4.2
Explanation:
To find the side length labelled "x" in the three given right triangles, we can use trigonometric ratios.

In the first right triangle, angle A = 59°, the side adjacent angle A is b = 5, and the hypotenuse is labelled "x". Therefore, we can use the cosine ratio to find the value of x.




Therefore, the value of x is 9.7, rounded to the nearest tenth.
In the second right triangle, angle A = 79°, the side adjacent angle A is b = 10, and the side opposite angle A is labelled "x". Therefore, we can use the tangent ratio to find the value of x.




Therefore, the value of x is 51.4, rounded to the nearest tenth.
In the third right triangle, angle A = 72°, the side opposite angle A is b = 13, and the side adjacent angle A is labelled "x". Therefore, we can use the tangent ratio to find the value of x.




Therefore, the value of x is 4.2, rounded to the nearest tenth.
